(BARSTOW, Calif.) — A desperate search is underway in Barstow, California, for a 2-year-old boy who was swept away by floodwaters Thursday evening, authorities said. The father and son became separated from their vehicle as flood waters carried them northward, police said. The incident occurred during a day of severe weather that brought powerful thunderstorms to Southern California. Local volunteers from the Desert Recovery Group and community members joined the search effort, according to authorities. “We have a bunch of volunteers out here who are still looking,” Xavier’s aunt, Leanna, told ABC News station KABC-TV.
